This invention relates to improvements'in means: of attachment for jwindow shades, Y awnings, and the like totheir supporting rollers, and has asfits essentialobject simple, Binexpensive, and? effective detachable anchorage of thejshad'eto the mum;

A furthervobject is the provision of such means of detachable anchoragewhile affordo ing substantialuniformity, in smoothness of the rolled shade, which, considered nega tively, includes theavoidance of appreciable lateral projections at'the places of anchorage;

i 'With these and other objects in view as will inpart hereinafter become apparent andin part be stated, the invention contemplates direct and. effective anchorage in thematerial of the roller by which-.a shade is adapted to s be easily, quickly, and inexpensively detach- 7 fably mounted so that replacement can be iefiectedwith facility. f

' 1 z'lh-e invention also comprises certain other nov l constructions, combinations, and ar rangements of partsas subsequently specified v y and claimed. 7 '1 'In theaccompanying drawings,+' v

1 Figures 14;, '15," 16, and 17 are detailed,

fragmentary plan views of parts of shades illustratingvarious forms of openings adapted to cooperatewith the'fasteners or attaching means', I Figure 18 is a perspective View of a modified embodiment of fastenerf Ithas heretofore been proposed to detach-., ablyconnect a shade toa roller by expensive 7o and unsatisfactory "exp'edients, including either the grooving or other special shaping of the roller and the'emplo'yment of encircling spring clamps or the provision of de-' tachable' attaching means cooperating'with a permanently attached strip. Among theva a,

rious objects of the present invention is the detachable anchorage of a shade to a roller'by means penetrating the material of the roller Q. i

and directly engaging the shade without re quiring any special grooving or other shaping of theroller and without interposition of any permanently attached strip. Numerous detailed'means may be employed for accom v plishingthis result, some of the successful forms of which are illustrated in the accompanying drawings.

"R ferring to the drawings by numerals, 1 indicates an ordinary, conventional roller which is indicated'as a window shade roller, but may be any appropriate shade roller, such as employed for awnings, and the like. Mounted on the roller 1 is the'shade 2 which, while shown as a windowshade roller, may

be any other appropriate shade including i For each aperture 3 a fastener, as seen in detail in Figure 3, is employed consisting essentially of a center part or body): from which projects the roller-engaging prongs 5, 5, and the shade-engaging prongs 6, 6. The

. prongs 5 are preferably formed with pointed,

inner ends for enabling easy penetration of the wood or other material of'roller 1, and,

in order toinsure effective anchorage while using comparatively short prongs 5, the free ends of the prongs 7.5 are preferably shoul-- dered to produce arrowheads 7, 7; Thus,

when the prongs are forced into the material v of the roller 1, the shoulders of the'arrow heads 7 will resist withdrawal owing to the spring of the wood fiber across the shoulders of the arrow heads as the latter enter the material of the roller. Hence, it is practicable to employ comparatively short prongs 5 while affording dependable anchorage, and this is especially desirable in that type of roller hollowed out to contain an operating spring as is common practice wlth shade rollers.

In applying the fastener after the prongs 5 havebeen forced intothe material of the roller 1 to the required extent, the prongs Gare bent to an outstanding position, as seen in full lines at the lefthand end of the roller in Fig- 7 ure 2. Obviously, as many. of the fasteners Obviously, when it becomes position seenat the ri 'hthand end portion or I Figure l. The shade and roller are then in condition for regular use;

desirable to replace a'used shade with anew one, it is onlynecessary to bend the prongs 6 ofthe several fasteners to the outstanding position,

withdraw the old shade, apply the new one,

' and bend the prongs back to, the outstanding position.

'The resulting combination of parts is especially effective for facilitating easy and inexpensive repa1r,.alterat1on, or modification. For instance, if light shades are desired during the winter and dark shades during the summer, the interchange can be made without the provision of new rollersor the tedious and trying task of removing permanent fasteners and refastening. In addition toithe actual labor of removing permanent fasteners, the question of effective alinement sometimes occasions difficulty, especially when the shade'is changed by an inexperienced hand. VVit-h the present invention'the fasteners would ordinarily be supplied on the shade rollers ready for use, and the operator would have only the simple task of buttoning th-e shade to the roller. 4

p In Figures 4 and 5 a modifiedzform of fastener is illustrated in which the buttoning operationgis accomplished without variation in the actual location of any part of thefastoner. In this structureoa collar or sleeve 8 is provided and carries an outstanding, button-like flange 9; Prongs 10 project edgewise from the collar 8 and function'the same as prongs 5 ofthe above-described fastener. When the fastener of Figures {1 and 5 is em ployed, the prongs 10 are forced into the material of theroller until the'inner edge of collar Sstrikes the roller, and the fastener is then in condition for use. Then this particular fastener is employed, or similarly shaped fasteners, the shade, as seen in Figure 17, is preferably provided with a keyhole opening or slot 11 for each fastener, the enlarged portion of each slot being substantially of the diameter of the button head r or flange 9 so that the shade can be easily dropped over the button and drawnlength wise until the collar 8 is located in the elongated portion of the key-hole slot. Obviously, the openinginthe shade may be otherwise formed, as, for example, it may be a slot 12, as seen in Figure 16, simulating a butv,

ton-hole. In that instance, the shade would literally'be buttoned over the several fasteners and the collars 8 would extend through the slots 12 while the flanges 9 would lie outside of the shade; The collar 8 is preferably co-mparatively short, being of a length substantially equal to the thiokness of the shade to be appliedor may be of a length equal to double that thickness in case a return fold of the shade is employedrr f I In Figures '6 and 7 'siillustrated a further embodiment in which-a collar 13is provided with the button flange 1a and is adapted to be secured to a shade roller by a tack or pin 15 having a headoverlying the flange 14, and

a shank extending through the collar and intothe material of the roller. l

In Figure 8 is illustrated a further'modified embodiment in which a button head 16 a is formed integral with a short shank 17 terminating in an extended reduced shank '18,'the short shank providing a stop shoulder, and the shank 18 being adapted to be driven into the material ofthe roller to a position; with the inner end of the shank 17 abutting against the surface of the roller.

:The operation of the parts of the structures seen 111 Figures 6 and 7 is thesame, after anchorage to theshade roller, as described above. with respect to the fastenerv of Figuresj l and 5. r j a In Figures9 and 10 is illustrated a further embodiment in which a collar 19 islprovided and a tack or pin 20 hasitsshank extending through the collar and through a turn button 21, so that the head ofthe :pin 20 retains the turn-button 21in engagement with the collar, The tack or pin 20 is driven into the material ofthe roller until the inner edge, of -collar 19 iss'eated against the roller,

and then theturn-button21 is preferably engaged by the shade by having the shade prothe respective slot in 'eachinstance, the turnbutton is turned at right anglesso as toex I 'tend'crosswise of the slot and'thus effectively anchor theshade to ,the roller. Obviously,

the arms of the turnkbutton 2 1 may be of sufficiently pliable material to enable the arms to be bent to an'o-utstanding position so as to function in the manner described with respect to the prongs 6 and to accordingly cooperate with an aperture 3.

In Figures 11, 12', and 15 is shown a further modified embodiment in-which a shade roller penetrating part carries a, spring prong adapted to bGlSpIUIig intojposition for tie tachably retaining a shade in engagement,

with a roller. In this structure, 1 indicates the roller and 22 the shankof the fastener,

' which shank may be constructed in any appropriate manner to provide efiective anchorage in the roller, the formshown includlng the provision of screw threads for the shank' 22. When the shank 22 is a screw, its head 23 'isprovided with theusual kerf and prefer ably formed integral with the headis a laterally-extending spring prong24 bent to have its'free end portion normally lie against the surface of the roller lwhen the fastener has its'shanlr seated in thematerial of theroller. The said'free endportion of prong 24 is preferably out-turned, as at .25, insufiiciently tooutstand as faras the balance of the strucar butsufficiently'to facilitate introduction of material between the free end of the prong I and ther-oller. WVhen employing this type of 40 fastener, the shade 2 maybe provided with an aperture similanto aperture 3, but is preferably formed with an aperture having a grommet or eyelet 3 to stabilize the connection between the sh adeand the fastener, and,

in the event of the use of such eyelet, the eye let is curved bodily to correspond to the curv- I ature of the surface of the roller, as clearly seen in Figure 11. In theoperation of the structure as seen-in Figures 11,12, and 15, the

shade is applied byhaving theseveraleyelets '3 introduced beneath the free ends 25 of prongs 24=and the parts drawn up untilthe eyelets surround the respective heads 23. The

prong 24in each instance ispr-oportionedto alfordasuificient space between the free end of the prong which contacts with the roller 1'. pro i the head of the-shank to accommodate an appropriate portion of the shade.

will resist tendency of the 'shade'to escape from its engagement incident to sudden retrogradem-ovemenfland the freeend portionof the prong 241: will effectively resist such tendency; i v

I Thus, when f the parts have been assemb1ed,the head 23.

. The spring'prong type of fastener is susceptible of qulte a wide range of variations two additional forms bein illustrated, respectively, in Figures 13 and roller penetrating parts are driven prongs rather than screw-threaded. In Figure 13, the shanks 22 areduplicated to produce a 18,inwhichthe. j .70

staple'23 having a laterally-extending spring prong24c terminating at 25 in an outstanding portion adapted to accommodate passage of a shade to position while the prong has its free end roller. I In Figure 18, the structure is quite similar to that seen in Figure 13, except that the parts are formed from sheet material instead of a body 23 and the body is formed with the" spring prong 24L having the terminus 25.- 2

the opening 3 so that portions of the material parts of the body of the of the shade overlie fastener.

What I claim is 1. The combination, with a shaderoller,

portion tending to rest against the I bent rod. The shanks 22 are carried by the f I of a fastener permanently anchored to the' roller for detachably attaching a shade, such fastener comprising a body outstanding from the roller, a prong extending from the body into the material of the roller and anchored drawal therefrom, and a prong exposed be-' yond the roller and located to rem-ovably overhang a shade engaging the outstanding body.

"2; The combination, with a shade roller, of

for detachably attaching a shade, such fastener comprising a body outstanding from the roller, a prong extending from the body into the material of the roller and anchored therein and having means of resisting with-, drawal therefrom, and a prong exposed beyond the roller and located to removably over- "hang a shade engaging the outstandingbody,

the prong being bendable to be moved to and from a position facilitating buttoning a shade over said body'. p

3. The combination, with a shade roller, of a fastener permanently anchored to the roller for detachably attaching a shade, said fastener comprising a spacer outstanding from the surface of the roller, a prong extending from the spacer into the material of the shade roller to provide permanent anchorage there-. to, and m'eans for detachably retaining; a v shade inengagement with said spacer. In testimony whereof I aflix my signature. i
